Photoelectric Phenomena in TiO₂ Glass Binder, x-H₂Pc dispersion Layer Prepared by Sol-Gel Method

Abstract

We have investigated the photo-effect of new organic-inorganic hybrid photoconductive layer prepared by so1-gel method. It is found that TiO₂ G1ass binder-x-H₂Pc hybrid layer prepared by sol-gel method has a UV quenching effect in the atmosphere. The photocurrent based on H₂Pc excitation light is quenched by overlapping UV light and is rapidly decreased to dark level UV quenching effect is caused by peculiar surface interaction at interface between p-type organic photoconductor and n-type inorganic photoconductor.
